TO WHOM IT MAY CONCERN:

Be it knownthat we, MILTON W. NnsMrrn and Geenen' W. NEs'MIrH, ofMetamora, in the county of Woodford, andA State of Illinois, haveinvented certain new and-'useful Improvements in Grain-Registers', andwe dry hereby declare that thefollowi'ng is a full, clear, andexac'tdescription thereof, reference being had'to the accompanyingdrawings, making part of this specification, and to the letters ofreference marked thereon, like letters indicating like parts whereverthey occur. l

To enable others skilled in the art -toeonstruct and use our-invention,we will proceed to describe it.

Our invention consists in a novel construction of an apparatus forregistering with accuracy and certainty, the quantity of grain measured,as it is delivered from threshingmachincs, or from bins or 'other placeswhere it may be stored. In the vdrawings-'fv Figure 1 is a perspectiveview-of theapparatus complete.

Figures 2, 3, and 4, are views oi'. the registering-mechanism detached,for the purpose of showing its con struction more in detail. A l A Inthe grain-growing regions ofthe country, it is. customary to employ theproprietors of threshing-machines to thresh th'c grain at a specifiedprice per bushel; .and it is desirable, both for -the owner of the grainand the thresher, 4to have lsome certain and acenratc'means ofascertaining the -exact quantity of the grain threshed, and also toprovide means for preventing either accidental or intentional errors inthe registrationof the amount or quantity. To accomplish these purposesis the objectief our invention, which is 'as follows:

Weprovide a box,`A, in'which we secure a registering orcounting-mechanism, enclosed in a suitable ease or box, B, providedwith'a cover, C, to exclude grain, dust, or other substances thatmightinterfere with the operation of the mechanism, this coverbeing -provided'with 'a small window, I, through which the numbers on theregistering-wheels may be seenwhen the box B is closed, these partsbeing shown in fig. 1.

The registering-mechanism consists of a serios of wheels, v, havingnumbers arranged in regular order en their peripheries, in theusualmanner. The outer one ofthe series of wheels v, is provided alsowith a series of ratchet-teeth, m', double in number to the number ofigures on said Wheel, and both this and all succeeding wheels of' theseries, except the last one, have,- projecting from their oppositesid'e, a pin, x, as shown in lig. 2, these wheels v all being mountedside by side, upon acommenjournal,` onv which they turn loosely, so thateach may be moved independent of the others. Upon a counter-shaft orjournal, c, we mount a corresponding series ofwlieels, u, which latterlare provided, on their periphery, with two sets of cogs, one setAcorresponding in number andsize with the cogs m, secured to each of thewheels o, except the'rst, and the other set being only one-third asnumerous, and disposed' at regular intervals, as represented in'iig. 4.These wheels Mare so placed that their first or lmore numerous series ofcogs will engage with the cogs 'm on wheels v, and thus turn the latterwhenever vthey themselves are moved, the wheels u being moved only whenthe pins x of wheels v are brought'around in contact with the cogs s,and-which can occur but once at each revolution of the wheels v, aspringpawl, h, being arranged to engage with the cogsof wheels u, andprevent their being accidentally turned, this arrangement of. thepartsbeing more clearly shown in iig. LZ. I

' -For operating Athese -Wheels-we provide alevcr, L, which 'is pivotedbya-journal, T, to the case B, in such u manner as to have the lever Lprotrude from the side of the case, as shown in figs. 1 and 2, for apurpose to he hereinafter explained. An arm, d, protrudcs from theopposite side of the journal T, from the end of which extends a rod,j`,connecting it with an, arm,'g, of a rock-shaft, G, as shown more clearlyiu iig. 3. To this rock-shai`t we secure a pawl, consisting of a frameor plates, P, between which is pivoteda dog, t, at e, this dog t beingprovided withlan arm, u', whichis arranged to strike against a' pin orstop, 1*, by` which its forward movement on its pivote is limited, aspring, n, being arrangedv to press against the rear or upper side ofthe dog t, and keep it pressed forward, l'except when pushedback, as'hereinafter explained. This pawl is so located,

vthat the dog t will engage with the ratchet-teeth m lon the rstwheel'v, s as to movel the wheel one notch every time the le'vcr L ismoved forward, there beings. spring, p, applied to the journal T, bywhich means the lever is thrown back as soon as released, after beingoperated, the dog t yielding, s o as to let its 'end pass by'one of theratchet-tceth m', as the leverL resumes its' position. -A springpawl, o,is so arranged as to engage with the rntchetteeth m','and thus preventthe wheel v from movingbackwnrd by any means.

With the mechanism thusconstructed and arranged, it will be seen thatwhen the lever L is operated twice, the iirst wheel v will be moved adistance equal to that at which the numbers on its periphery are placedfrom each other, this arrangement being adopted for the reason thatwhile the grain is measured in a half-bushel measure, it is desired toregister the number of bushels only. When'the wheel has thus been moveduntil the number nine is under the window I, the pin :r on said wheelwill havcpassed around, so as to be in contact with one of the teeth son the first wheel and 'as the wheel v is-moved so as to bring the nextligure under the'window, the wheel u will be moved with it, and as thislatter moves, it'will also carry with it-thcJiext dial-wheelfv thedistance of one-figure, after which the pin a: will b ev disengaged fromthe cog s, and pass on, leaving the other wheels remaining stationaryuntil the pin x shall have passed entirely around, when it will repeatthe operation, thus at cach revolution moving the adjoining dial-wheelone interval or` ligure. This operation is continued until the Aseconddial-wheel will have made one revolution, when its pin x will, in thesame manner, move the next dial-wheel one interval, and soon to anyrequired extent, the drawing represcntingbut three dial-wheels, which,with -the ten numbers on each, 'will register' as high as nine hundredand ninety-nine, which is -as much as can ever be requircd'iri any oneday by a threshing-machine. By adding to the series of wheels, thecapacity of' the machine may -be increased to any desired extent.

Having t'hus constructed our registering-apparatus, and secured it inits case, B, we secure the whole in a box, A, which box we make of sucha. size as to permittwo half-bushel measures, H, to be placed and easilymoved about therein, as representedin fig. 1. In the centre of the boxA, we place a post, D, at such a distance from the case B that themeasure H-can .be passed between the post and the case, and in so doingstrike against the protruding-.part of" the lever L,.and therebyoperatethe register.

' The operation' is as follows: The box is tobe placed under thedelivery-spout of the thresher, in such a position that the cleanedgrain may be received into one of the empty measures placed behind thelever L, as represented in g. 1. When the measure is full, it is drawnforward between the post D and the case B, striking thellever L as itpasses it, the otherv measure H being atthe same time placedv under thespout as the-full one is removed.4 The full one is emptied by theattendant while the other is being filled, and thus the process iscontinued, the registeringLapparatus thus indicating with accuracy thenumber of bushels measured. It is obvious that, if preferred, the spout-maydeliver the grain' in to the measure on the opposite side of thelever L, the latter,in that case,ubeing operatedby the empty measure'behind, as it is drawn forward to take the place of the full-one. y Itis also obvious that instead of. the box being made of such a size, withthe post D, to guide the measure in its movement,vthe box A may be madeof half the width, and the measures, as they are drawn forwariL-belifted outandvthen replaced, .one behind the other, thus accomplishingthe same object, theessential requisite being that the lever L shall beoperatedbyeac'h of the measures as-they are moved. Anysurplus grain thatmay chance to fall fromthe spout, and not be caught in the measures, orthat may be removed from the measure, in case it is allowed,by.accident,'to become too full, will be caught in the box'A, from whichit may be removed andmeasured-atvany time. The case B should be providedwithea lock, so that it cannot be opened, or the mechanism interferedwith by others; and there is apin, b, arranged to fit Ainto a hole, o',in front of the leverL, by which thelatter may be locked, andpreventedfrom' beingimoved when the machine is left, as will benecessary during meal times, nights, and other` times when theA workceases This pin b is shown in iig. 1, attached by a cord, and inserted,for convenience, in a hole in the end of the case, where it is vkeptwhen not required to lock the leverL. It is obvious that ourapparatus'may beusedwith equal facility for measuring and registeringgrain taken 'from bins, storehouses, and all similarlplaces, especiallywhere the grain is delivered 'through `a spout. i I

By these meansvwe provide an apparatus that is especially adapted: tothe wants of the community, that is reliable, and being portable, anddetached from `the threshing-machine, can be used with equal facilitywith any style or make of machine, and also independent ofthreshingmachines. for measuring grain elsewhere.

Having thus described our invention, what we claim, is

1. A. grain-measuring apparatusyconstructed substantially as described,and provided with a registeringdevice operated by a lever, so arrangedthat by drawing the measure past it in one direction` theregister willbe operated substantially as-described.

n 2. 'lheregistering-devic'e, consisting of the dial-wheels v, providedwith the pins ir, and having the gearwheels 'm attached,-in combinationwith the donblewheel u, when said parts are arranged as described, andoperated by the pawl P, as and for the vpurpose set forth. Y

8. The pawl P, having the dog t, with the stop r and spring n, allarranged substantially as described.

4. The combination of the registering-device, the pawl P, and theleverL, all arranged to operate as and for the purpose set forth.
